Solución de problemas de conectividad de SQL con Microsoft Entra Connect

En este artículo se explica cómo solucionar problemas de conectividad entre Microsoft Entra Connect y SQL Server.

La siguiente captura de pantalla muestra un error habitual, si no se encuentra SQL Server.

SQL error

Pasos para solucionar problemas

Abra una ventana de PowerShell e importe el módulo ADSyncTools de PowerShell

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Import-module -Name "C:\Program Files\Microsoft Azure Active Directory Connect\Tools\AdSyncTools"

Nota:

Install-Module requiere la actualización a PowerShell 5.0 (WMF 5.0) o una versión posterior;
O instale la versión preliminar del módulo PowerShell de PackageManagement - marzo de 2016 para PowerShell 3.0/4.0

  • Mostrar todos los comandos: Get-Command -Module AdSyncTools
  • Ejecute la función de PowerShell: Connect-ADSyncDatabase con los siguientes parámetros
    • Servidor. Nombre del servidor SQL Server.
    • Instance. (Opcional) El nombre de instancia de SQL Server y, opcionalmente, el número de puerto, que le gustaría utilizar. No especifique este parámetro para que use la instancia predeterminada.
    • UserName. (Opcional) Cuenta de usuario con la que se conectará. Si se deja en blanco, se usará el usuario con la sesión iniciada actualmente. Si se conecta a un servidor SQL Server remoto, debe usar la cuenta de servicio personalizada que ha creado para la conectividad de SQL de Microsoft Entra Connect. Microsoft Entra Connect usa la cuenta de servicio de sincronización de Microsoft Entra Connect para autenticarse en un servidor SQL remoto.
    • Password. (Opcional) Contraseña para el nombre de usuario proporcionado.

Esta función de PowerShell intentará enlazar con el servidor SQL Server y la instancia especificados mediante las credenciales pasadas o usar las credenciales del usuario actual. Si no se encuentra el servidor SQL Server, el script intentará conectarse al servicio SQL Browser para determinar los puertos y protocolos habilitados.

Ejemplo con solo un nombre de servidor:

PS C:\Program Files\Microsoft Azure Active Directory Connect\Tools> import-module .\AdSyncTools.psm1

PS C:\Program Files\Microsoft Azure Active Directory Connect\Tools> Connect-AdSyncDatabase -Server SQL1

Ejemplo con un número de puerto e instancia que no existen:

PS C:\Program Files\Microsoft Azure Active Directory Connect\tools> Connect-AdSyncDatabase -Server SQL1 -Instance "INSTANCE1"

TROUBLESHOOTING: Attempting to query the SQL Server Browser service configuration on SQL1.
Get-ADSyncSQLBrowserInstances : Unable to read the SQL Server Browser configuration. An existing connection was forcibly closed by the remote host. 
Ensure port 1434 (UDP) is open on SQL1 and the SQL Server Browser service is running.

WHAT TO TRY NEXT:

Each SQL instance must be bound to an explicit static TCP port and paired with an inbound firewall rule on SQL1 to allow connection. Enable the SQL Se
rver Browser service temporarily on the SQL server and run this cmdLet again to further troubleshoot the issue. Alternatively use the SQL Server Configur
ation Manager on SQL1 to verify the instance name and TCP/IP port assignment manually. 

You must specify both the instance name and the port to connect when the SQL Server Browser service is not running. An inbound firewall rule on SQL1 is required for the associated port.
	Example: 'MySQLInstance,1234' where 1234 has a matching firewall rule.

TROUBLESHOOTING: Attempting to query the SQL Server Browser service configuration on SQL1.
SQL browser response contained 2 instances.
Verifying protocol bindings and port connectivity.
MSSQLSERVER     : Enabled - port 1433 is assigned and reachable through the firewall
INSTANCE1       : Blocked - the inbound firewall rule for port 58379 is missing or disabled


WHAT TO TRY NEXT:

Each SQL instance must be bound to an explicit static TCP port and paired with an
inbound firewall rule on SQL1 to allow connection. Review the TcpStatus field
for each instance and take corrective action.


InstanceName : MSSQLSERVER
tcp          : 1433
TcpStatus    : Enabled - port 1433 is assigned and reachable through the firewall

InstanceName : INSTANCE1
tcp          : 58379
TcpStatus    : Blocked - the inbound firewall rule for port 58379 is missing or disabled
